NAV not working

hi,

 

would like some help in the matter..i bought a version of NAV2010 at a store and it came with a cd drive. i installed it in my laptop and used the product key provided to register it...it worked fine initially for the couple of months until i noticed that the NAV icon wasnt in the desktop anymore until a couple of weeks ago..i checked the files and it was still installed, problem is when i go to the NAV icon and click on it is not working..i still have 260 days left on it and i cant run the live update nor can i scan any files..woulld anyone know if can could reinstall it again wihout paying for it?i dont want it to go to waste because theres still a lot of days in its protection..Thanks!
